Which Labour MP has spoken only once since August

As people know, it was falsely alleged that Bob Clarkson had made no contributions in the house since August, except some interjections.  In fact he had made three speeches on bills and asked one oral question.  This it seems, is a mere trifling error, but enough on that.

It got me thinking about certain Labour mps, so being bored I went hunting.  And I found one Labour MP who has made only one contribution in the House, since August.  Yep 1/4 as many as Bob (or 1/9 if you count interjections but I don't).

Now who can guess the MP?

UPDATE: There is more than one of them. Another Labour MP has made zero contributions since August.

Oh and just found a third who has done just one speech.

So that makes one Labour MP who have made zero contributions in the House since August and two who have made just one speech.  Make your guesses below.

UPDATE2: This original post was about Mahara Okeroa, a Minister, who had made only one contribution to parliament since August. It was because The Standard had falsely claimed Bob Clarkson had made no contributions since August, and he had actually made four.  It got me thinking about whether any Labour MPs had made less than four.  After the original post appeared (note the title is about which MP spoke once, not none), I carried on through Hansard and also found two other MPs who had made few contributions since August and updated the post.  One was Dover Samuels and the other George Hawkins.  A commenter helpfully pointed out Mr Hawkins had had cancer for surgery, which of course explains for him his lack of contributions.  While I didn't name Hawkins in the main body of the post, I would not have included him had I been aware of his sickness and am sorry for doing so.  The moment it was brough to my attention I posted in the comments that it was of course a very good reason for the lack of contributions.
